getSupportFragmentManager（）是未定义的
我收到以下错误： “在下面显示的片段文件中， ”getSupportFragmentManager（）方法未定义为typesnew View.OnClickListener（）{}“ 。
我有通过ABS引用的兼容性库和正确的导入。 我重新安装ABS库w /兼容库，清理项目，重新启动Eclipse，但没有任何工作。
本质上，我试图让片段显示一个dateselect器通过一个对话框片段。 一旦selectdate，它必须返回到片段，以便它可以用来计算基于该date的信息。
这是我的片段的代码：
package com.owentech.abstabsviewpager; import android.app.Activity; import android.app.Dialog; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.Button; import android.widget.Toast; import android.support.v4.app.DialogFragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.app.FragmentActivity; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentTransaction; import com.actionbarsherlock.app.SherlockFragment; public class ObstetricsFragment1 extends SherlockFragment{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { //Fragment Layout View view = inflater.inflate(R.layout.obstetricsfragment1, container, false); Button mPickLMPDate = (Button) view.findViewById(R.id.pickLMPDate); mPickLMPDate.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { LMPDatePickerDialogFragment d = LMPDatePickerDialogFragment.newInstance(); d.show(getSupportFragmentManager(), "dialog"); } }); return view; } public Dialog onCreateDialog(Bundle savedInstanceState) { // TODO Auto-generated method stub return null; } } 这里是对话框片段的代码：
package com.owentech.abstabsviewpager; import android.app.Dialog; import android.os.Bundle; import android.widget.DatePicker; import android.app.DatePickerDialog; public class LMPDatePickerDialogFragment extends ObstetricsFragment1 implements DatePickerDialog.OnDateSetListener { static LMPDatePickerDialogFragment newInstance() { LMPDatePickerDialogFragment d = new LMPDatePickerDialogFragment(); return d; } private int mLMPYear; private int mLMPMonth; private int mLMPDay; public Dialog onCreateDialog(Bundle savedInstanceState) { return new DatePickerDialog(getActivity(), this, mLMPYear, mLMPMonth, mLMPDay); } public void onDateSet(DatePicker view, int year, int month, int day) { mLMPYear = year; mLMPMonth = month; mLMPDay = day; } }
最后，这里是我的活动的代码：
package com.owentech.abstabsviewpager; import java.util.ArrayList; import android.content.Context; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import com.actionbarsherlock.view.Menu; import com.actionbarsherlock.view.MenuInflater; import android.widget.TextView; import com.actionbarsherlock.app.ActionBar; import com.actionbarsherlock.app.SherlockFragmentActivity; import com.actionbarsherlock.app.ActionBar.Tab; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.app.FragmentTransaction; import android.support.v4.app.Fragment; import android.support.v4.view.ViewPager; public class Obstetrics extends SherlockFragmentActivity { ViewPager mViewPager; TabsAdapter mTabsAdapter; TextView tabCenter; TextView tabText; // START Action Bar Menu Items @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getSupportMenuInflater(); inflater.inflate(R.menu.main_menu, menu); return super.onCreateOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) { switch (item.getItemId()){ case R.id.menuLog: ChangeLog cl = new ChangeLog(this); cl.getFullLogDialog().show(); return true; case R.id.menuEmail: Intent emailIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("mailto:support@medicaldoctorapps.com")); startActivity(emailIntent); return true; case R.id.menuRate: Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=appinventor.ai_shawn_m_gee.MedicalDoctor")); startActivity(browserIntent); return true; case android.R.id.home: // App icon in action bar clicked; go home Intent intent = new Intent(this, Home.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(intent); return true; case R.id.menuExit: this.finish(); return true; default: return super.onOptionsItemSelected(item); } } //END Action Bar Menu Items // START Tabs View Pager (Add tabs by adding mTabsAdapter.addTab) @Override public void onCreate(Bundle savedInstanceState) { // Information you want returned to your application, via onCreate(), if the activity is destroyed and restarted due to some implicit reason super.onCreate(savedInstanceState); mViewPager = new ViewPager(this); mViewPager.setId(R.id.pager); setContentView(mViewPager); ActionBar bar = getSupportActionBar(); bar.setDisplayHomeAsUpEnabled(true); bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); mTabsAdapter = new TabsAdapter(this, mViewPager); mTabsAdapter.addTab( bar.newTab().setText("Wheel"), ObstetricsFragment1.class, null); mTabsAdapter.addTab( bar.newTab().setText("Physical"), HistoryPhysicalFragment2.class, null); mTabsAdapter.addTab( bar.newTab().setText("ROS"), HistoryPhysicalFragment3.class, null); mTabsAdapter.addTab( bar.newTab().setText("CAGE"), HistoryPhysicalFragment4.class, null); mTabsAdapter.addTab( bar.newTab().setText("SIGECAPS"), HistoryPhysicalFragment5.class, null); mTabsAdapter.addTab( bar.newTab().setText("Glasgow"), HistoryPhysicalFragment6.class, null); mTabsAdapter.addTab( bar.newTab().setText("Neuro"), HistoryPhysicalFragment7.class, null); mTabsAdapter.addTab( bar.newTab().setText("Dermat"), HistoryPhysicalFragment8.class, null); mTabsAdapter.addTab( bar.newTab().setText("Minicog"), HistoryPhysicalFragment9.class, null); } public static class TabsAdapter extends FragmentPagerAdapter implements ActionBar.TabListener, ViewPager.OnPageChangeListener { private final Context mContext; private final ActionBar mActionBar; private final ViewPager mViewPager; private final ArrayList<TabInfo> mTabs = new ArrayList<TabInfo>(); static final class TabInfo { private final Class<?> clss; private final Bundle args; TabInfo(Class<?> _class, Bundle _args) { clss = _class; args = _args; } } public TabsAdapter(SherlockFragmentActivity activity, ViewPager pager) { super(activity.getSupportFragmentManager()); mContext = activity; mActionBar = activity.getSupportActionBar(); mViewPager = pager; mViewPager.setAdapter(this); mViewPager.setOnPageChangeListener(this); } public void addTab(ActionBar.Tab tab, Class<?> clss, Bundle args) { TabInfo info = new TabInfo(clss, args); tab.setTag(info); tab.setTabListener(this); mTabs.add(info); mActionBar.addTab(tab); notifyDataSetChanged(); } @Override public int getCount() { return mTabs.size(); } @Override public Fragment getItem(int position) { TabInfo info = mTabs.get(position); return Fragment.instantiate(mContext, info.clss.getName(), info.args); } public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } public void onPageSelected(int position) { mActionBar.setSelectedNavigationItem(position); } public void onPageScrollStateChanged(int state) { } public void onTabSelected(Tab tab, FragmentTransaction ft) { Object tag = tab.getTag(); for (int i = 0; i < mTabs.size(); i++) { if (mTabs.get(i) == tag) { mViewPager.setCurrentItem(i); } } } public void onTabUnselected(Tab tab, FragmentTransaction ft) { } public void onTabReselected(Tab tab, FragmentTransaction ft) { } } // END Tabs View Pager }
您将通过使调用对话框的活动扩展FragmentActivity来摆脱此问题
public class ObstetricsFragment1 extends FragmentActivity{
这是支持库所固有的，如对话规格和支持库规范所示
尝试将您的代码更改为：
public class ObstetricsFragment1 extends SherlockFragment{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { //Fragment Layout View view = inflater.inflate(R.layout.obstetricsfragment1, container, false); Button mPickLMPDate = (Button) view.findViewById(R.id.pickLMPDate); mPickLMPDate.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { LMPDatePickerDialogFragment d = LMPDatePickerDialogFragment.newInstance(); FragmentManager fm = ObstetricsFragment1.this.getSherlockActivity().getSupportFragmentManager(); d.show(fm, "dialog"); } }); return view; }
我在Marco的回答中做了一个差异，看看他实际上build议的变化：只是
d.show(getSupportFragmentManager(), "dialog");
至
FragmentManager fm = ObstetricsFragment1.this.getSherlockActivity().getSupportFragmentManager(); d.show(fm, "dialog");
如果有人使用SherlockActivity而不是SherlockFragment只需将活动扩展到SherlockFragmentActivity 。
加载一个课程项目（ https://developer.android.com/training/multiple-threads ）有类似的问题。
为了解决，我不得不添加一个外部的jar（sdk / extras / android / support / v4 / android-support-v4.jar）。
希望这可以帮助。
您需要从SherlockDialogFragment扩展ObstetricsFragment1。
在片段调用getChildFragmentManager()获取FragmentManager 。 看到这个
改变这一点
mPickLMPDate.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { LMPDatePickerDialogFragment d = LMPDatePickerDialogFragment.newInstance(); d.show(getSupportFragmentManager(), "dialog"); } });
至
mPickLMPDate.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { LMPDatePickerDialogFragment d = LMPDatePickerDialogFragment.newInstance(); d.show(getChildFragmentManager(), "dialog"); } });
您的项目中存在一个问题，因为您使用的是不推荐使用的actionBarSherlock …您应该查看Android支持并使用它，因为supportFragmentManager可用。 使用它很容易，将它添加到您的build.gradle
compile "com.android.support:support-core-utils:25.2.0"
在使用FragmentActivity或Fragment扩展你的活动和片段后， 也许你会因为使用sherlock酒吧而有所改变
关于你的问题的另一件事是，你从一个片段调用supportFragmentManager …你应该调用
getChildFragmentManager() // because it will be a nested fragment
希望这是有帮助的
